Sean Mackrory commented on BIGTOP-716:
--------------------------------------
I just got bitten by another more subtle way that a non-BASH default shell can
get in the way: when we invoke scripts with "sh <script name>" inside other
scripts. We should specify BASH in those locations too.
> standardize on bash as a shell of choice

> 90% of development and testing of our scripts happens with bash, however, if
> we don't enforce {noformat}#!/bin/bash{noformat} and just specify
> {noformat}#!/bin/sh{noformat} instead on some of the systems we may end up
> running against #!/bin/dash and other bash alternatives. This could lead to
> subtle problems.
